"Battery Health Management" reduces the Full Capacity and Remaining Capacity of the macbook pro battery ?

Hi, as subjected above,


My device is MacBook Pro Retina 15" 2017.

The current information for the battery health is :


Design Capacity = 6669 mAh

Full Capacity = 6500 mAh

Remaning Capacity = 6476 mAh


Charge cycle = 25 (I plugged in the device from sunday to friday, and remove the charger at saturday, let it use its battery, then until 25%, I plug in / charge it again, that's why it's count as 1 charge cycle per/week, so from the day it was brought back from Apple Store until today, it is 25 charge cycle / 25 weeks)


Since I am using my macbook pro plugged in all the time, and also the battery was replaced with new battery from Apple Store at the end of December 2019 (for keyboard issue so all the top case was replaced), is it the Battery Health Management features reduce the Full Capacity and Design Capacity ?


As it is informed that the Battery Health Management may cause battery's maximum charging capacity be limited.


Is it what happen to my device right now since the full capacity is lower that the design capacity and even the remaining capacity is lower than full capacity ?


Thanks

MacBook Pro 15″, 10.15

This all seems the new normal—



macOS Catalina 10.15.5 introduces battery health management, a feature designed to improve the lifespan of your Mac notebook's battery.


The Battery Health button appears in >SystemPreferences>Energy Saver —this feature is limited to Mac laptops with Thunderbolt 3 ports. That equates to all MacBook Pro models released since late 2016 and the Retina-capable MacBook Air models released since 2018.

@ leroydouglas


yes, i know that macos catalina introduce battery health management feature, and i've just updated it a few weeks ago and just now i notice the battery issue.


In my case, is it a normal behaviour of the battery or is it because of the battery health management feature ?


It is 97% now, after 25 cycles and 6 months, is it supposed to be like that, or it is because of the battery health management feature ?
